Without the extra memory of Opt 003 installed, the maximum supported resolution on an external monitor is 1280x1024. With Opt 003 installed, the maximum supported resolution on an external monitor is 1600x1200, but at 75Hz, which isn't supported by all monitors. With a 1600x1200 or 1920x1200 monitor which supports 60Hz but not 75Hz, it is possible to use a video scaler to convert between the 16700-series 1600x1200 at 75Hz output to 1600x1200 or 1920x1200 at 60Hz. I tried this today with an Extron DVS 304 DVI video scaler and got decent results with 16700-series 1600x1200 output on a 1920x1200 at 60Hz monitor. I've had mixed results between different Extron video scalers. I couldn't figure out how to configure an Extron DVS 510 to give the same results in this scenario as the DVS 304 DVI.

If it's hooked up right, a logic analyzer can also be a powerful software debugging tool. The first time I saw a logic analyzer was in the hands of a DEC software engineer (Anton Chernoff, I think) who had one hooked up to a PDP-11's console buses. It was amazing to see execution captured in real time, giving much more power than ODT ever had. Meanwhile, on logic analyzers: I have a Fluke (Philips) PM3585 analyzer at home, unfortunately short on pods so I can use only about 32 of the 96 channels. It's pretty flexible, has lots of channels, and (in state-only mode at least) a decent amount of memory. No plugins, just a single box. It's not as well known so the price may be lower, I haven't checked. paul
[cctalk] Re: Logic Analyzers - HP/Agilent 16700B or 1670G?
I have both, and I end up using the 1670G most of the time because it is so much more convenient. The acquisition cards on the 16xxx keep failing too.

[cctalk] Re: Logic Analyzers - HP/Agilent 16700B or 1670G?
In any case, when it comes to eBay sellers of logic analyzers, be very careful. I remember asking a seller about a particular HP LA where the claim was made as "working". But oddly, no test pods were pictured. I asked the seller about that and the reply was "We don't have pods, but when we powered it on, we got a display.,.." Something akin to selling a used car as "working" because the engine runs. --Chuck

I had a Telcon Zorba that had a number of problems which I worked through with a scope and DMM (shorted diode and bad HOT on the video board, bad 8275 CRT controller chip), before I had to break out the LA. Along with the source code for the BIOS, I was able to use the LA to find a bad 2N3904 in the interrupt chain for the floppy drives, and finally an 8254 Programmable Interval Timer with a dead counter. Without the LA, it would have been a much longer repair process. Mike Loewen mloe...@cpumagic.scol.pa.us Old Technology http://q7.neurotica.com/Oldtech/

I wouldn't pay more than $150 for an empty 16700B, $250 for an empty 16702B and if you have patience I suspect you could get a 16702B with multiple cards for $350 (sometimes with some really nice cards). Now whether the cards work is another question. Pricing is all over the place but prices have definitely falling over time. Hi Tony! I got the impression that people were finding them for around $100 - $300 back then. The prices I see on Ebay currently are all much higher. Certainly lower then when they were new though. Perhaps it's because I have only been looking about a month and my primary source is Ebay. Currently on Ebay, that I can see, the cheapest I see is a 16702B with a couple of 16712A cards and no pods/probes for $300 plus $120 shipping and tax. The 16712A are the absolute minimum I think that would be useful at 100Mhx and 8K/16K memory. I'd still have to find at least 2 sets of pods and probes. https://www.ebay.com/itm/225682194711 The next cheapest is a 16700B for $430. It has 4 interface cards but the listing doesn't say what they are. But it's local pickup only https://www.ebay.com/itm/314745893438 Then there is a 16702B for $449.99 which looks like and has a 16715A card and pods. But the detail listing says "failed self test for: VRAM Serial Access Memory Inputs Test, VRAM Serial Port Cell Test, and System Clocks (Master/Slave/Psync) Test." Not sure if that's bad but is sounds like it. https://www.ebay.com/itm/155632931934 And so on. Am I looking in the wrong spot? Thanks, John H. Reinhardt

I most love the option to mix and match cards in these units. I built mine by grabbing it and a 16500 that has some cards I wanted, swapping and keeping the best, selling the rest.

There are a few modern LCDs that can make use of opt B if your unit has it. I think I have a pattern gen card and one low end acquisition card. Else the chassis are empty. The difficulty with the 1670x is the cards (acquisition and scope, not pattern). They form corrosion under the runners. I had 10 or so cards go bad over a 5 year period. All now have visible corrosion. I'm slowly working my way through removing the runners, fixing the corrosion and repairing damaged traces. There are no schematics but there is a very helpful active repair thread on eevblog. In my personal machine my second scope card passes diagnostics but totally fails calibration. Otherwise the diagnostics are pretty good but they don't run at boot up so most sellers have no clue how to run them. Try setting up a distance based search on eBay. I suspect something will show up given a few months patience but if it includes cards there is a very good chance they are bad. Don't ever buy a card on eBay "for parts or repair" unless it's dirt cheap. Good luck > >

There have been a few threads very recently in https://groups.io/g/HP-Agilent-Keysight-equipment which you would probably find interesting. There is a lot of enthusiasm over the 1670 and 16700 machines - I wouldn't say you've missed the sweet spot since these are now often much cheaper than the later 168x and 169x machines but still very well liked : not least because the 167x are based on HPUX rather than Windows.

Hi Glenn, Thanks for chiming in. I've seen you post often on the EEVblog about various LA. I knew I forgot something. I'm in the Fort Worth, Texas area. So middle of the country length-wise but down South. I've seen shipping on Ebay range from "included" (which is kind of scary) to $350 and "freight". My bench space right now is kind of limited but I'm hoping in a few years (retirement) I'll have a bigger space to poke around in. The 1670G is interesting in that way. There seems to be a pretty complete one (Options 002 and 003 - OSC and memory) on Ebay but that's the place that's charging $350 for shipping. -- John H. Reinhardt

That can have a large impact on the cost of acquiring a large 16700-series logic analyzer. For example, I have more of those than I need in the Seattle area. A local deal might work out well, but if shipping is involved that can quickly get too expensive. If bench space is limited, a 1670G takes up a lot less, and is completely self contained and easier to move around and set up. On the other hand, a 16700-series is more flexible, and if you have space to set up an external monitor you can see a lot more data on the screen at the same time without scrolling around.
